Check_MK Werk 5227: Checkgroup humidity: Fix swapped lower levels and definition of only one kind of levels

ID: 5227 Title: Checkgroup humidity: Fix swapped lower levels and definition of only one kind of levels Component: Checks & agents Level: 1 Class: Bug fix Version: 1.5.0i1 Previously, all checks of the checkgroup humidity would crash if only lower or only upper levels were configured. Lower levels configured in the GUI would be swapped in the check, ie the warn level would be interpreted as the crit level and vice versa. This has been fixed.
